Aim 2- To Test if Longshore drift is taking place along Deal Beach on the Day of our visit and if so in which direction the Longshore Drift is taking place.

Aim 2a

For this aim, we measured the wave angle. To do this, I laid a protractor on the floor, and watched for about 5 minutes in which direction the waves were travelling. I would look down on the protractor, and note down the angle of the waves. I then worked out the average angle.

We had to do measure the wave angle because it would show us in which direction the longshore drift (if any) was taking place, therefore resulting back to the title of the aim.

Aim 2b

Weather Data:

Wave Angle       = 150º

Wave Direction  = South East

Wind:

On the day of the visit, the weather conditions were probably the worst conditions of the week. There was rain early on in the morning and when we arrived, so we had to wait in the minibus for the rain to stop. It did, and so we could carry out our investigation. The temperature was 59 º, so not very warm. The cloud cover was about 80%, so not much sunshine at all.

To measure the wind speed, I used an instrument called Anemometer (fig.3). I basically held this instrument up in the air, and the wind would blow onto its fan, and it would measure the speed for me. To measure the wind direction, I held my handkerchief up in the air, and recorded using a compass, the direction the handkerchief was facing, and went to the opposite of that because that would be the direction the wind was coming from.

As you can clearly see from my results, the wave direction and wind direction are exactly the same. This is correct because as we know, the wave direction is affected by the wind direction.

Aim 2c

The purpose of the aim is to see whether Longshore Drift is taking place on the day of our visit and if so, in what direction.
